A woman has been arrested on suspicion of murder after the death of a child in Swansea. A murder investigation was launched after emergency services were called to a house in the Gendros area of the city on Thursday evening. South Wales police said the 41-year-old woman was being held in custody in Bridgend. Police said the child and the woman lived together and detectives were not looking for anyone else in connection with the death. An incident room has been set up and the investigation is being led by the force’s major crime investigations team. Ch Supt Chris Truscott, the divisional commander for Swansea and Neath Port Talbot, said: “This is a distressing incident which will be a shock to the local community. Detectives are working to establish the circumstances of the child’s death and there will be an increased police presence in the area to offer reassurance to local residents. “Speculation on social media is unhelpful and will cause distress to those affected by this incident at an already difficult time.”
